Genesis 17:12Meaning & Commentary from the Church Fathers

God also establishes the appropriate time for the act of circumcision. He commands, "Eight days from birth, let every male child born in your household and bought with silver be circumcised." This directive signifies that all within your domain are to receive this mark. To further illuminate the matter and assure you, beloved, that circumcision does not enhance spiritual value, let us examine the context. Why does God specify, “Eight days from birth, let … every child be circumcised”? It seems that the compassionate Lord chose this timing for two main reasons: first, to make the experience of circumcision more manageable for the immature, and second, to demonstrate that the act itself provides no spiritual advantage but serves merely as a sign.

Initially, God established the law of circumcision when He instructed Abraham, saying, "But you shall keep My covenant, you and your seed after you in their generations; and this is My covenant which I covenant between you and Me, and between your seed after you in their generations: Every male shall be circumcised, and you shall circumcise your foreskin, - and it shall be (this) a covenant between me and you, and your every male child shall be circumcised on the eighth day" (Gen. 17:9-12). By articulating this law and mandating its observance, God indicates that while such a law may seem trivial, it serves as a fundamental archetype for a significant sacrament. He elaborates further, asserting, "And My covenant shall be upon your flesh for an everlasting covenant, but the uncircumcised male whose foreskin is not circumcised on the eighth day, his soul shall be destroyed from her seed, because he has broken My covenant" (Gen. 17:13-14). Hence, the Apostle Paul emphasized that circumcision was granted to the patriarch as a sign and seal of faith in the uncircumcision (Rom. 4:11). His primary objective was to demonstrate that the calling and justification through faith precede and prevail over the statutes of the law as given by Moses. This, he believed, would embarrass the Israelites, convincing them that justification through faith is not a transgression of the law, but a return to what existed prior to it.

Applying this argument to contemporary relevance, Paul introduces a different form of circumcision. He advises the Jews to abandon their reliance on physical lineage by writing, "For he who is not a Jew outwardly is not a Jew; nor is circumcision that which is outward in the flesh; but he is a Jew who is one inwardly, and circumcision is that of the heart, in the spirit, not in the letter, whose praise is not from men but from God" (Rom. 2:28-29). Indeed, he seeks to divert their perspective on circumcision, encouraging them to regard it as increasingly spiritual rather than merely a physical rite (Rom. 4:11). Therefore, we must explore the true meaning of spiritual circumcision — what it represents in the flesh and why it is commanded to be performed on the eighth day specifically.

It is beyond doubt that if we desire to achieve communion with God through Christ, we must undergo purification and sanctification in every aspect. The divine directive given to Moses serves as an apt illustration: "Come down, testify to the people, and sanctify them today and tomorrow; and let them wash their garments, and be ready for the third day, for on the third day the Lord will come down upon Mount Sinai" (Ex. 19:10-11). Through the required sanctification, we see God's desire for us to cultivate a righteous disposition, and the act of washing signifies the cleansing of our physical bodies, which serve as the garments of our souls (Lev. 19:2).

Thus, those who sought communion with the Holy One were expected to undergo thorough pre-consecration, affirming His command: "Be ye holy, because I am holy" (Lev. 19:2). Consequently, the physical act of circumcision symbolizes this sanctification. Yet how does this become effective? By examining our inner selves, we find that pleasure is the precursor to all sin. Sin is often instigated by intense desires that lead our souls astray, suggesting an inclination to fulfill intentions through sinful action. James illustrates this truth by stating, "Let no one say when he is tempted, 'I am tempted by God,' for God cannot be tempted by evil, nor does He Himself tempt anyone. But each one is tempted when he is drawn away by his own desires and enticed. Then when desire has conceived, it gives birth to sin, and sin, when it is full-grown, brings forth death" (James 1:13-15).

It is within these lusts that the seeds of depravity take root, and it is through sinful pleasures that sin is first initiated. Hence, the Lawgiver instructs the removal of the foreskin, which is the origin of lust, teaching a profound lesson about purity. We cannot be truly cleansed if we do not abandon the sordid desires that stem from our hearts, armed with the true sword of the Spirit (Heb. 4:12). If this embodies the essence of true circumcision, it is rightly said to those who rely solely on physical flesh, "Circumcise yourselves to the Lord, and take away the foreskins of your heart, you men of Judah and inhabitants of Jerusalem" (Jer. 4:4).

The one who is circumcised in the flesh is merely circumcised for physical reasons alone, but true circumcision in spirit through faith in Christ leads to a connection with God. We receive spiritual circumcision on the eighth day, which signifies the resurrection of the Savior, establishing that spiritual circumcision brings forth life through participation in Christ, in line with Paul's affirmation: "For you died, and your life is hidden with Christ in God; when Christ who is our life appears, then you also will appear with Him in glory" (Col. 3:3-4).

Indeed, we can assert that those who sacrifice worldly pleasures for God must consequently die to worldly desires. This sentiment is echoed by Paul when he states, "But God forbid that I should boast except in the Cross of our Lord Jesus Christ, by whom the world has been crucified to me, and I to the world" (Gal. 6:14). By partaking of the Spirit, which removes all impurities, we must die to worldly pursuits and strive for a more virtuous life dedicated to God.

Therefore, circumcision occurs on the eighth day in honor of Christ's resurrection, and not before, for it is after His resurrection that the Spirit has been given. Jesus blew on His disciples, saying, "Receive the Holy Spirit" (John 20:22). While it is necessary for the Jews to practice physical circumcision, they remain bound under the punishing law symbolized through iron, while we, as liberated spirits, seek spiritual cleansing, which eradicates the filth of our souls by faith.

The ultimate goal of spiritual circumcision unveils itself when we reflect on the patriarch Abraham. At ninety-nine years old, the Lord deemed it appropriate to institute circumsion, which reveals itself as a precursor to the completion of virtue. In this light, the number one hundred symbolizes perfection, marking circumcision as a necessary step towards it. Indeed, spiritual circumcision becomes essential even for those liberated in Christ. A true believer in Christ is he who has liberated himself from the devil's bondage and the yoke of sin, having "broken their bonds," as it is written (Psalm 2:3), and donned the glorious truth of Christ's faith.

As we explore sacred scripture, it becomes evident that the eighth-day circumcision is designated for the free and not for those still enslaved. Ishmael, birthed by Abraham through Hagar, was circumcised not on the eighth day but on the thirteenth year, demonstrating that he represents the earthly and enslaved side, disconnected from the fulfillment of the eighth day, which symbolizes accepting the saving message of the resurrection presented in Christ's gospel. The disobedience of the nation of Israel remained outside both the eighth and twelfth days, as they remained unresponsive to the apostolic teachings.

In contrast, Isaac, the child of promise, received circumcision on the eighth day, representing the free sons of the heavenly Jerusalem. These children of freedom, in alignment with the resurrection of Christ, attain spiritual circumcision, liberating them from both sin and death, which ensures communion with Christ.

When we turn to Exodus, we see that spiritual circumcision embodies the destruction of death and the abolition of decay. Moses, under divine instruction, was tasked with confronting Pharaoh, leading to Israel's liberation. According to Scripture, "It happened that on the way, at a lodging place, an angel sought to kill him. But Zipporah took a sharp stone, and circumcised her son's foreskin, and said, 'Surely you are a bridegroom of blood to me.' So He let him go" (Ex. 4:24-26). This incident illustrates the pivotal role of circumcision, whether physical or spiritual.

The angel, intending to strike Moses, withdrew upon encountering the blood of the circumcision performed by Zipporah, which begs a profound contemplation of the hidden truth. The spiritual circumcision of the new covenant community wields a divine power that repulses the destroyer, whereas the physical circumcision alone, bound to ancestral heritage, could not shield Moses from death.

How then does Israel, unaffected by spiritual circumcision, continue to endure? The answer lies in their unwillingness to accept Christ's resurrection; as such, death remains their consequence. Conversely, those who embrace faith in the resurrection inherit grace, extending the promise of spiritual circumcision to all. A marked distinction exists between the resurrection experienced by believers and non-believers; the former who honor Christ and His justifying act will attain the resurrection of life, whereas the latter will confront condemnation.

The spiritually circumcised community extends grace to the faithless, facilitating divine mercy that aims to redeem all creation. Paul's reflection on disobedience illustrates that the grace offered to the faithless can return to the faithful, thereby multiplying the grace of Christ. Ultimately, the Apostle Paul reveals the mystery of future resurrection by stating that Christ is the firstfruits, rising first from the dead, with those who are His at His coming (1 Cor. 15:23). This underscores that the promise of resurrection is primarily designated for those united in faith, though it benefits creation at large due to God's goodness and desire to abolish death entirely.

Notice that Zipporah circumcised not with iron but with sharp stones, symbolizing the non-punishing aspect of the New Covenant, reflecting Christ's solidity and unyielding nature. The Father, through the prophets, refers to Christ as "an adamant stone," indicating His steadfast presence among His people (Am. 7:8). The divine Jesus, following Moses, purified the Israelites for battle against their enemies and provided them with the necessary preparation through spiritual circumcision. Thus, it is written: "And the Lord said to Joshua, 'Make yourselves flint knives and circumcise the sons of Israel'” (Josh. 5:2-3). The "stone" here signifies the immutability and strength of God's Word.

As Paul describes the Word as "living and powerful, and sharper than any two-edged sword" (Heb. 4:12), this illustrates its ability to penetrate the heart and cleanse impurities. Through this divine action, one becomes holy and blameless. The circumciser, Jesus, together with those circumcised under Him, highlights those innocent of wrongdoing, as it is written, "the young child who does not know good or evil" (Deut. 1:39).

The Israelites who emerged from bondage faced God's wrath for their disobedience, which prevented them from entering the Promised Land. However, their children, free from that guilt, exemplify the new nation through whose faith we receive spiritual circumcision in Christ. The instruction to circumcise beyond the Jordan, where the new generation enters into covenant with God, signifies the importance of spiritual rebirth.

Following their circumcision, the Lord declared, "Today I have rolled away the reproach of Egypt from you" (Josh. 5:9). What then does this signify? It symbolizes liberation from slavery, the cruelty of sin, and the burdensome task of making bricks. The power of spiritual circumcision, conveying restoration and freedom from sin, elevates the soul above demonic oppression.

This spiritual circumcision makes a believer a partaker of the Divine Nature through communion with our Savior Christ (2 Pet. 1:4). As the Israelites fulfilled the Passover and feasted on the land's produce, they experienced the transformative power of the Gospel by first crossing the Jordan and receiving spiritual circumcision, which cleansed them of the shame of Egypt.

As Abraham is summoned to embrace perfection, he is endowed with the divine transformation of completeness. The command states to circumcise all males and to remove the foreskin of the flesh. True circumcision is of the spirit, as evidenced by the instruction to circumcise the hardness of one's heart, as mentioned in Deuteronomy 10:16 LXX. This passage is often interpreted to mean that one should circumcise their mental faculties since the mind is more powerful than anything else. Furthermore, since the male is considered sacred, it is declared that every firstborn son shall be consecrated to the Lord (Ex. 13:2).

God established the practice of circumcision for Abraham, his household, and all future generations stemming from him. This rite serves as a foreshadowing of Christian baptism, symbolizing repentance and the putting to death of sinful desires, as well as the severing of all wicked actions. Furthermore, circumcision is emblematic of the resurrection. Just as God commanded that newborn males be circumcised on the eighth day, so too will all humanity rise from their graves on the Day of Resurrection, emerging as if reborn from the womb, ‘will be renewed like an eagle's youth’ (Psalm 102:5). This event will follow the seven temporal ages of the world, representing the eighth day, the beginning of eternal life. At that moment, all the corruption inherent in human flesh will be entirely removed. As the Apostle has noted, “It is fitting that this corruptible be clothed with incorruption, and this mortal be clothed with immortality” (1 Cor. 15:53).

The eighth day is significant. According to Aristotle, it is only after the completion of seven days from a child's birth that one can confidently determine its vitality. In Scripture, the number seven symbolizes a profound sense of fulfillment, with anything that falls short of this number viewed as lacking. For example, offerings of animals to God could not occur until seven days post-birth (Ex. 32:30). The circumcision held on the eighth day may be understood as a representation of the renewal of humanity through Christ's Resurrection, occurring within the completion of the seven days, as well as possibly signifying the purification of creation over God's seven days.

“The offspring shall be circumcised for you daily.” Circumcision is to be conducted at a designated time to prevent any opportunity for delay, and not too soon after birth, allowing the child to become robust enough to endure the challenging procedure and reach the necessary maturity. In the Scriptures, the number seven symbolizes completeness and perfection; items that fall short of this number are regarded as lacking. Thus, animals were not to be presented to God until they had completed seven days post-birth (Ex. 22:30). It was also crucial not to delay too long, so that parents could swiftly find joy in seeing their child enter into a covenant relationship with God.
